FIELD OF INVENTION

The present invention relates to the field of portable electronicdevices such as palmtop computer systems and cellular telephones.Specifically, the present invention relates to a device combiningportable computer system technology and cellular telephone technology.

BACKGROUND OF THE INVENTION

As the components required to build a computer system have reduced insize, new categories of computer systems have emerged. One of the morerecent categories of computer systems is the portable or “palmtop”computer system, or personal digital assistant (PDA). A palmtop computersystem is a computer that is small enough to be held in the hand of auser and is thus “palm-sized.” As a result, palmtops are readily carriedabout in a briefcase or purse, and some palmtops are compact enough tofit into a person's pocket. By virtue of their size, palmtop computersystems are also lightweight and so are exceptionally portable andconvenient.

The emergence of the cellular phone technology in the last few years hasrevolutionized the telecommunications industry. Where in the pasttelephones were largely confined to homes, offices, and other stationarystructures, cellular phone technology has made it possible for phones tobe truly portable and exist nearly anywhere there are people.

Recently, the technology behind both palmtop computer systems andcellular phones has advanced to the point where it is proposed tointegrate cellular phone capabilities into a palmtop computer system.However, both types of devices possess different modes of operation. Forexample, palmtop computer systems are handheld devices providingprimarily a visual experience while cellular phones are held to the headof a user and provide primarily an auditory experience.

Integrated palmtop computer systems/cellular phones present concernsregarding accessibility and immediacy. Typical integrated palmtopcomputer systems/cellular phones limit a user's accessibility to eachdistinct function of the device. For example, a user is required to holda cellular phone to their face, thereby restricting the use of the PDAfunctions, which require a user to be able to look at the device.

Furthermore, a cellular phone requires an immediate response to anincoming call, or the user risks missing the call. For example, a callerwill only wait a matter of seconds for a person to answer their call,otherwise they will hang up. If a user is using the PDA function of anintegrated palmtop computer system/cellular phone and receives anincoming call, the user must stop using the PDA functionality in orderto answer the call.

In some integrated palmtop computer system/cellular phones, a user maynot be able to operate the two devices at the same time. For example, auser operating the device as a cellular phone may desire to write a noteor make an appointment on the PDA. At a minimum, the user will be forcedto pause the phone call. However, the user may not be permitted tooperate the PDA functionality while the device is being operated as acellular phone, thus limiting the accessibility of the PDAfunctionality.

The form factor of the device plays a crucial role in whether or notusers are comfortable operating the device. For example, manufacturersbelieve that some cellular phone users may be hesitant to use a cellularphone that is in the shape of a palmtop computer system. Likewise, atypical cellular phone display does not offer the size or interfacefunctionality that a palmtop computer system does. The users of palmtopcomputer systems and cellular phones desire the benefits of each of therespective devices, and are unlikely to sacrifice these benefits ifforced to compromise the form factor of the device.

SUMMARY OF THE INVENTION

Accordingly, a need exists for an electronic device that is both apalmtop computer system and a cellular phone. Furthermore, a need existsfor the above electronic device to allow for the immediacy required foranswering a phone call and still allowing for the accessibility ofapplications running on the palmtop computer system. A need exists forthe above electronic device to provide the benefits of both a palmtopcomputer system and a cellular phone in one integrated device byallowing for common operations and functionality without compromisingthe form factor of either device. These and other objects and advantagesof the present invention will become obvious to those of ordinary skillin the art after having read the following detailed description of thepreferred embodiments which are illustrated in the various drawingfigures.

Embodiments of the present invention are directed to a compact removablevoice handset for an integrated palmtop computer system/mobile phone.The present invention may be used in conjunction with a palmtop computersystem (e.g., a personal digital assistant (PDA)). The PDA compriseselectronics for wireless communications and a contact informationdatabase and a receiving slot for storing the handset.

In one embodiment, the handset is the overall length dimension of thePDA and is compact such that when placed in the receiving slot, there isminimal increase to the overall size and weight of the PDA. The presentinvention comprises a microphone and a speaker, and is communicativelycoupled, via either a wireless connection or a wired connection, to thePDA. In one embodiment, the wireless connection is established by meansof a Bluetooth transceiver located in both the handset and the PDA.

In one embodiment, the handset comprises control elements allowing it tobe operated independent of the PDA. In one embodiment, a control elementis used to control the volume of the speaker. In another embodiment, acontrol element is used to access a contact information database locatedin the PDA. In another embodiment, a control element is used to initiateor terminate wireless communications. In another embodiment, a controlelement is used to switch between volume control and database accessactivities.

In one embodiment, the handset comprises a display. In one embodiment,the display is operable to display record information of the contactinformation database stored in the PDA. In another embodiment, thedisplay is operable to indicate the volume level of the handset. Inanother embodiment, the display is operable to indicate whether there isan incoming phone call.
